JOSEPH GILBERT, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO ELIZABETH GILBERT AND N. T. MORSE, OF SAME PLACE.

FIRE-PROOF BUILDING.

SPECIFICATION forming part of Letters Patent No. 237,382, dated February 8, 1881.

Application filedDecember 9, [880. (No model.) A

To all whom it may concern:

Be it known that I, J OSEPH GILBERT, a citizen of the United States, residing in the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Fire-Proof Buildings, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a side elevation of a span embodying my invention. Fig. 2 is a bottom view thereof. Fig. 3 is an end view thereof.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of metallic lathing connected to the beams or girders of buildings so constructed that when the plaster is applied a level ceiling is formed and the bases of the beams are protected from the direct action of fire, the invention also being applicable to partitions, the connection of the lathing to the beams being by means of hangers which are suspended from the beams and have base strips or pieces Which support or sustain the lathing.

Referring to the drawings, A represents I or flanged beams or girders for buildings.

B reprepresents metal hangers, which are suspended from the base-flanges of the beams, and to them are connected transversely-extending strips 0, of metal, separated one from another, on which are placed and secured longitudinally-extending slats D, of metal, separated one from another, it being noticed that the hangers are bent around the flanges, and their upper embracing portions are held in position by the skewbacks E, and spaces exist between their lower portions and the bases When the plaster is applied it is effectively clinched or keyed by the slats, and likewise so by the slats and strips, whereby the ceiling formed is level and secure throughout. Or the invention may be applied to partitions, in which case the parts are set at a rightangle to that shown, and a flat wall is produced possessin g all the advantages of the ceiling. Furthermore, the bottoms of the base flanges of 55 the beams are'covered by and sheathed with the plaster, whereby fire is prevented reach ing and acting against said flanges, and thus the beam is guarded and protected from distortion, being inaccessible to the fire.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The beams, in combination with hangers B, having transversely-extending strips 0 and the longitudinally-extending slats D, substantially as and for the purpose set forth.

2. The beams, in combination with the h an gers, having upper embracingportions and bottom strips, the skewbacks, and the metallic lathing, substantially as and for the purpose set forth.

JOSEPH GILBERT.
